Definitions
- the most important innovation here is to encase the steering wheel rim as far as possible with a large number of sensors or a sensor grid structure and the supply lines through a joint in this sensor surface to lead inwards.
- the wrapping can be interrupted along a line along the rim surface in order to guide a multiplicity of feed lines inwards there. So even a very high number of grid lines can be guided in there to then be continued eg in a separate plane along the steering wheel rim.
- the surface of the steering wheel rim ring body can be covered as far as possible with a fine-resolution sensor structure, so that for virtually all points on the steering wheel rim fine shifts of fingers in any direction can be measured and also the high number of supply lines is housed in the construction.
- the installation of X-lines and Y-lines crossing at small distances allows a measurement of individual fingers in their exact position and, moreover, the measurement of complex contact surfaces, ie a real multi-touch, to variants of the
- a multi-channel technology on the steering wheel rim enables true multi-point multi-touch measurements, so that ideally finger and hand contact surfaces are measured.
- the variants proposed here solve problems that occur due to the special shape of the torus-shaped steering wheel rim: Large

- a sensor-matrix structure is thus brought into the shape of a tubular ring or tubular ring element.
- Supply lines of the sensor levels are led by joints inwards under or in a shield.

- the structure can be deformed for this purpose or in a later method step or in a plurality of method steps in order to form the steering wheel rim surface.
- the sensor structure may be preferred but not exclusive
- Embodiment can be realized as a capacitive effective grid of X-lines and Y-lines. These grids are either made of small crossing conductors or they also have surface extensions within their plane to increase the capacitive effect. These extensions are especially diamond shapes.
- touch or proximity sensitive sensors on a steering wheel rim or on a steering wheel element associated with an electronic control unit characterized in that it can detect touches or approaches by fingers or hands that are finely resolving in their surface position on the steering wheel rim surface can be differentiated by a sensor structure in the form of a plurality of sensor elements or a matrix structure on the steering wheel rim surface areally spread and shaped three-dimensionally. Their leads are led inwards under the surface and under a shield or in a shield.
- a multi-channel sensor technology is needed.
- Such a sensor consists in particular of sensor structures, supply structures and

- Fig. 2 shows the embodiment as Fig. 1 increases. Visible is the inner three-layer structure 170 with three levels: the support layer 171 for sensor structures, the flat or grid-like shielding plane 172 and the
- the contact pieces such as 160, 161, 162 can be designed in variants: As bending or folding of the carrier material 171 and 173 including conductors in particular 180 ° or as vias between two layers or as a line piece.
- the contact 160 is connected to the feed line 180 on the carrier layer 173.
- the leads to the sensor structures can be guided in their course so that the distance of these respective leads is approximately equal and the distances to each adjacent leads are approximately equal to keep the capacitive properties of the lines approximately similar. Due to the relatively long paths along the steering wheel, this compensation can be e.g. facilitate and improve the work of a capacity-data evaluating processor.
- this path compensation can be fulfilled by having a plane with conductor structures having specific paths of the individual conductors:
- FIG. 3 shows such an exemplary embodiment of an important variant of the inner feed line layer 173 shown here in unwinding, corresponding to the layer deformed in FIG. 2.

- the ladder crosses the rectangle, which is, in particular, shaped like a tube.
- the conductor of the farthest entrance should, as far as possible, be like a diagonal.

- the intervening conductors have accordingly
- a blind conductor 301 is additionally shown as a loop running back and forth, which acts for the internal conductor 180 as a capacitive parallel.
- the conductors can also - in slightly different gradients - in turn compensate for different conductor lengths elsewhere, as in the path to the steering wheel spoke afford.
- this lead layer 173 can also be rolled into itself or folded once or multiply together with a shielding layer in order, for example, to guide it in a cavity.
- a shielding layer in order, for example, to guide it in a cavity.
- You can also in such a layer for the individual conductors produce respective shields, for example by additional printed conductors, so that quasi many coaxial cables are formed.
- a shielding structure e.g. 172 under the sensor structures can also serve as an electrical heater by being generated by a closely reciprocating conductor as a grid structure and e.g. operated with direct current. If necessary, another shielding level 190 may be installed inwards or downwards, so as to be capacitive
- a sensor structure can simultaneously serve as a heater if the plurality of individual conductors, e.g. each powered by separate power sources that supply DC or a much lower frequency than the sensor voltages. You can make the individual conductors to the continuous heating conductor by connecting them via inductive frequency barriers.
- Sensor structures or leads or shields or combinations thereof may consist of carrier material with conductive structures applied on two sides.
- a substrate e.g. plastic trays, film, foil or textile or fabric, coated on both sides with e.g. Y-lines and X-lines printed or vaporized or woven, holds both structures in position to each other, even in subsequent deformation steps.
- sensor structures or feed lines or shields can generally be deformed together with a carrier material or inserted or woven in or cast in or embedded in a carrier material, or these methods can be combined.
- Sensor structures or shields or leads may be fabricated together with substrates by a series of deformation steps.
- FIG. 4 shows an exploded exemplary plane structure with matrix area extensions in the not yet completely deformed state for a steering wheel element 400: Upper sensor lines such as 430, 431, 435 on carrier material 440, lower Sensor lines such as 450, 451 and an inner lead plane with lines such as 480, 481.
- the three-layer structure 470 contains at the top and bottom each a carrier material level and a shielding plane therebetween. It is bypassed in the later remaining gap of the sensor surface by curved or folded
- it may include an inner shield 490 and a cover 420, and e.g. give a leather case 410.
- FIG. 5 shows layer-by-layer planes for a steering wheel 500 as an exemplary embodiment of a sensor array with surface extensions: upper sensor lines such as 530, 531, lower sensor lines such as 550, an inner lead plane with lines such as 580, 581 and shielding plane 572 and substrate 571 and 573.
- it may include an inner shield 590 and a cover 520 and eg give a leather cover 510.
- the tube-like sensor is shielded from its own tube-like leads.
- a sensor is created as a multilayer structure, bent or folded at the later equatorial, then bent laterally in the direction of a circular cross-section, ie curved in the direction of a pipe or pipe element and then to the ring body or curved ring element deformed or eg brought by assembly on the steering wheel in this form. It can e.g. also appropriate shell shapes or partial shells are created and mounted.
- a multi-layered three-dimensional pre-formed construction can be placed in a form which remains somewhat elastic so that it can be mounted, e.g. from 2 tubes in semicircular shape with cut at the inner equator or 4 half-tubes in semi-circle form or 8 quadrant half-tubes.
- two-sided with conductor structures such as a plurality of sensor elements or a matrix structure or with leads or with Shielding provided carrier such as plastic shell, film, foil, textile or fabric
- the leads can be folded under the lower sensor plane, with a shield plane placed between these two planes. This placement can also be done by the folding process, for example.
- the two-sided laddered carrier can hold both sensor planes in precise position with respect to each other and at the same time integrate further: If in particular, unlike in FIGS. 1, 2, 4 and 5, the sensor plane with the higher number of lines, with as meridians running lines, is laid up and together with their leads, eg. As shown in Fig.
- this multi-layered structure can be shaped three-dimensionally.
- This deformation can in principle be subdivided into partial deformation steps, for example in a bend of the construction to the half-tube and its curvature to the annular body. This eventually leads to e.g. Half or quarter circle segments of shells to be applied in a further step on the circular steering wheel.
- Film or films or similar plastically deformable carriers should have the shape produced have a certain opening along the equator to be elastically mounted and to facilitate the elastic closure on the steering wheel.
- the later circular cross-section of the annular body can e.g. stay open about a 75 ° angle, which is first bent up elastically when mounted on the steering wheel to
- the manufacturing method may in another, non-exclusive variant as a method step include the introduction of conductors in the material volume of a foamed steering wheel blank.
- the lowest level or subsequent several levels of the entire structure can be created in individual steps.
- lower level shields or leads or the lower sensor structure may be incorporated into the foamed steering wheel blank, e.g. be introduced by wire insertion.
- one or more levels of the sensor, lead, and shield structures may pass through into a volume of material, such as a sheet.
- Plastic foam introduced conductors are manufactured.
- prefabricated conductor structures for sensors in particular for supply lines or shields, can be poured or foamed into the steering wheel blank before the abovementioned steps.
- a combination is, for example, the variant with the following steps: First, the lower conductive structures are foamed, then the middle conductive structures introduced into the raw material body and then applied to the upper conductive structures, which are deformed together with their support material.
- the upper structures are in particular Y-lines, in another variant Y and X-lines as Sensor structures or in another variant, this together with the shielding directly below.
- Such hybrid variants combine carrier material with printed or applied conductor structures and carrier material with introduced, woven, foamed or cast-in conductor structures.
- the upper sensor structures are applied to the underside of a carrier material, in particular a shell, foil or a textile or fabric - in another variant woven there - and the lower sensor structures are in a carrier material such as Foam of the steering wheel blank inserted or foamed.
- a carrier material such as Foam of the steering wheel blank inserted or foamed.
- the sensor lines In contrast to the variant as shown in FIG. 1, in this hybrid variant it makes sense to arrange the sensor lines with a smaller number running along the rim at the bottom: for example, they can be used as wire without frequent settling in the material Ring body are laid. Then it makes sense to produce the sensor lines with a high number, which run transversely to the wreath, ie in meridians, with deformable carrier material.
- Carrier material may be provided in its supply line part on the opposite side with a shield, for example by flat or close-meshed, grid-shaped printed Ladder or woven ladder.
- the moldable carrier material has here on one side of the leads and on the other side shields.
- the leads can be rolled or folded to accommodate them in the cavity and are at the same time guided between an internal shield.
- this part of the feed lines in or on the carrier material can be designed such that the capacitive effects due to the respective line lengths and distances from one another remain approximately the same for the respective conductors, see FIG. 3.
- Such a shield may e.g. be created by laid or foamed or cast conductors.
- Supply lines can be laid in a cavity. This can e.g. a channel-like cavity along the steering wheel rim, which runs under a shield which is incorporated in the material or cast or foamed.
- a feeder structure e.g. In Fig. 3, in one variant, along with one or two corresponding shielding planes may be rolled or folded in the direction of the short side to guide them in a cavity channel along the steering wheel rim.
- the proposed three-dimensional structures can basically also be used for sensors with resistance measurement, piezoelectric measurement or other.
- the disclosed solutions encase the surface of the ring body with a largely continuous fine-resolution sensor structure.
- a coherent, as far as possible continuous sensor structure is proposed, which not only consists of individual segments but also covers the surface as far as possible and evenly.
- touch events of individual fingers can be detected, also real multi-point multi-touch with many contact points, so that finger and hand contact surfaces are distinguishable.
- Parting shells produced in the manufacture of the sensor can also be compensated for: the post-processing or software can supplement the spatial assignment of sensor areas, e.g. the succession of points along a meridian. And it can be a e.g. Halves the sensor line with two parts electrically equalized by joints and thus make the joint ineffective. Thus, a virtually seamless recognition of touches or approaches is possible.
- Three-dimensional deformations of the sensors and supply lines can be compensated by algorithms or self-calibration of new processors.
- a fine-resolution multi-channel sensor can be produced in a further embodiment by placing conductor structures in groups of different ones
- Course directions produce a sensor matrix, in particular by two conductor groups at an angle, rotate in opposite directions, three-dimensionally.
- two groups of oppositely skewed conductors produce a sensor matrix by running at two different depths and forming a plurality of common crossing points.
- a group consisting of 20 ladders starts from a meridian, runs obliquely over the ring body and intersects with the other group of eg 20 skewed ladders by running in a different direction around the wreath.
- This oblique direction corresponds for example to a developed quadrant of the steering wheel, which arises on its developed steering wheel rim surface as a diagonal, for example an angle of about 20 °.
- a sensor can be equipped with two steering wheel spokes
- a group of conductors can wrap the wreath largely, together with the second group of conductors creates a planar sensor matrix, which in plan view, for example. diamond-shaped pattern results. Both conductor groups in opposite directions at an angle around the ring body form a matrix. For example, at one
- these ladder can be deflected and run to the steering wheel spoke.
- the group of upper lines such as 130, 131 e.g. each deflected by 20 ° to the left on the surface 140.
- the lines of this group thus run in this view to the left turning around the ring body.
- the group of lower lines such as 150, 151 can, instead of starting from the inner equator of the ring body on the right, be cut from the one shown here in the picture
- the lines of the second group begin at the meridian and run counter-clockwise, e.g. 20 ° to the right deflected over the levels 170.
- a rhomboid-like matrix is formed by both line groups with intersecting angles of about 40 °.
- this variant is a different resolution of the sensor in the two directions of its surface.
- Advantage of this variant is that one does not need a multiplicity of contacts like 160 and no long internal supply lines like 180, 181.
- the supply lines stay here at the meridian. There they can, for example, in analogy 1 to the equator of FIG. 1 at the edge of the meridian cut here in the image:
- the conductors arriving at the meridian can in particular be deflected inwards and / or severely narrowed and run to the spoke.
- this skewed-line matrix can also be used
- This skewed variant can basically be produced as a film, film, textile or fabric, e.g. in the sense of a printed foil tube or a knitted tube.
- Circumferential lines must be connected to a parting line through contacts and continued if necessary.
- An adequate, robust production method are obliquely opposing circumferentially inserted wire groups.
- Lines or leads going to a ring meridian as the meridian of connection can be there, e.g. in analogy to the deflection of the conductors at the inner equator of Figure 1 and Figure 2 are deflected at the edge of the meridian cut there in the image: arriving at the meridian ladder such as 130, 131 or the inner as 180, 181, 185 may in particular be deflected downwards or inwards, eg so that they are bent or folded under the sensor structure and / or severely narrowed, continue annularly along the meridian and finally in particular run through a joint at the inner equator of the annular body to the spoke in the direction of the processor.
- the inner conductors such as 180, 181, 185 can also already be deflected on the support 173 in the direction of the meridian and guided closer.
- the conductors arriving at the connection meridian such as 130, 131 or in FIG. 4, the conductors such as 430, 431 and 435:
- a deflection can already take place as a curve on the carrier material 171 or 440, in particular by approximately 90 ° in the direction of the meridian annulus, so then continue ring along the meridian lead.
- it can change the carrier material with the conductors by folding by 45 ° its direction.
- it can Contacts are made to other conductors, which then run along the meridian.
- said supply lines are guided inwards in relation to the sensor surface by being guided downwards to the annular body or before the assembly of the entire sensor, before the deformation step. This happens in particular by being folded under the lower layers of the sensor structure, in particular by a folding by 180 ° at the edge, which then ultimately corresponds to the meridian circular ring. This facilitates production from film, film, textile, fabric or the like. Otherwise, here are e.g.
- a slight increase in the thickness of the entire structure at the connection meridian can be compensated in particular by a corresponding slight recess in the steering wheel blank.
- the carrier material with the leads is e.g. curled or folded in a cavity of the steering wheel blank, e.g. runs annularly along a meridian.
- Shielding levels are placed between.
